Abstract A programme of research is introduced on the effects
on stream ecosystems of land-use change from native forest to pasture, and
subsequent re-afforestation with exotic pine plantations. The results detailed
in the 11 accompanying papers conclude that land-use change has had strong
effects on many key physical, chemical, and biological aspects of stream
ecosystems in and adjacent to Whatawhata Research Centre, near Hamilton, New
Zealand. Six of these papers compare streams, draining catchments with similar
topography, geology, and soils, to investigate land-use effects on stream
lighting, water quality, channel morphology, benthic and hyporheic habitat and
faunas, fish, and food webs. Two papers investigate hypotheses on the influence
of shade and crayfish using streamside mesocosms. Finally, three papers use the
experimental sites to evaluate methods for studying crayfish populations,
stream carbon pathways, and a stream temperature model. These studies provide a
comprehensive description of land-use effects on physical, chemical, and
biological characteristics of streams and contribute to the basis for future
long-term ecological research on the effects on streams of sustainable land
management practices.
